How to choose the magnification?
Latest company news about How to choose the magnification?

First of all, the magnification is determined according to the observation target, not the bigger the better. Novices generally like to increase magnification without thinking, but it’s not necessarily good. In particular, profiteers can get 1000 times or even tens of thousands of times according to the psychological chaos of novices, and those who really have a little understanding of telescopes may directly reject such telescope when they see this kind of propaganda, because it is certain that these telescopes are rubbish.

Generally speaking, the magnification of products from regular manufacturers is generally not more than twice the caliber (caliber in mm), otherwise the magnified image is not clear and it is meaningless, of course, it is not absolute, and it is also related to personal feelings. If the quality of the primary lens is not good, the various aberrations and even the magnification of the aperture cannot be reached (caliber unit mm), such as some inferior short-focus general elimination, etc.,


Even if the optical quality meets the requirements, the magnification is higher than 300 times. Generally, the influence of atmospheric vision on imaging should be considered. When the view is good, 600 times is almost close to the limit. In some areas, the best visual field conditions may reach 1000 times, but Ordinary users will not encounter it. Even higher magnifications have to rely on adaptive optics.


Regarding the magnification, in fact, it depends on your observation target. It is better to enlarge the observation target to about 2/3 of the field of view of the eyepiece. If the target is dim, the aperture support is needed at this time, but this is not to increase the resolution and magnification, but to increase the light-gathering power by the aperture.

1. The magnification is generally divided into three levels, the medium magnification is 6 to 10 times, the large magnification is 10 to 20 times, the variable magnification is from 20 to 40 times for Chinese and German, and 25 to 40 times for domestic products.
2. The greater the magnification of the telescope is not the better, if the magnification exceeds 10 times, it should usually be installed on a tripod.
3. The larger the aperture, the larger the predicted field of view and the greater the brightness, which is conducive to observation under dim light. Generally, it can be selected between 30 and 50 mm according to needs.
4. Most ordinary telescopes on the market use plastic lens bodies and barrels. Only a few high-end products adopt all-metal structure, which are expensive but sturdy and durable.
